Authentication method using biometric information and electronic device therefor

Abstract

An authentication method using biometric information and an electronic device. An authentication method using biometric information in an electronic device includes: receiving biometric information from an external electronic device. An authentication is performed for the received biometric information by comparing the received biometric information with biometric information stored in the electronic device. An authentication result us transmitted to the external electronic device such that the external electronic device performs a predesignated operation.

What is claimed is: 
     
         1 . An authentication method using biometric information in an electronic device, the authentication method comprising:
 receiving, by the electronic device, biometric information output from an external electronic device;   performing by the electronic device an authentication for the received biometric information by comparing the received biometric information output with biometric information stored in the electronic device; and   transmitting by the electronic device an authentication result to the external electronic device such that the external electronic device performs a predesignated operation.   
     
     
         2 . The authentication method of  claim 1 , wherein the biometric information comprises one or more of iris information, fingerprint information, voice information, and pulse information. 
     
     
         3 . The authentication method of  claim 1 , wherein the biometric information is received from the external electronic device using a short range wireless communication scheme. 
     
     
         4 . The authentication method of  claim 1 , wherein the biometric information is received by the electronic device in a form of raw data. 
     
     
         5 . The authentication method of  claim 1 , wherein the biometric information is received by the electronic device in a processed form using any one of coding or encryption. 
     
     
         6 . The authentication method of  claim 1 , wherein when the external electronic device is a Point Of Sales (POS) device that requests a payment, the authentication result comprises at least one of payment information or security information. 
     
     
         7 . The authentication method of  claim 1 , wherein when the external electronic device comprises a wearable device that interworks with the electronic device for authentication, wherein the authentication result comprises an instruction of controlling an operation of the wearable device, the instruction comprising at least one of an unlocking instruction and an application execution instruction. 
     
     
         8 . The authentication method of  claim 1 , wherein the receiving of the biometric information by the electronic device comprises receiving identification information of the external electronic device together with the biometric information. 
     
     
         9 . The authentication method of  claim 8 , wherein the transmitting of the authentication result by the electronic device comprises, after performing the authentication for the received biometric information, transmitting the authentication result to the external electronic device according to the identification information of the external electronic device sent with the biometric information. 
     
     
         10 . The authentication method of  claim 1 , wherein the transmitting of the authentication result to the external electronic device comprises:
 determining when the authentication is performed whether a user of the external electronic device and a user of the electronic device are the same; and   when it is determined the user of the external electronic device and the user of the electronic device are the same, transmitting the authentication result to the external electronic device such that the external electronic device performs the predesignated operation.   
     
     
         11 . The authentication method of  claim 10 , wherein the determining of whether the user of the external electronic device and the user of the electronic device are the same comprises by comparing at least one of biometric information other than the biometric information, account information, or sensor information. 
     
     
         12 . An electronic device for performing an authentication method using biometric information, the electronic device comprising:
 a communication interface that receives from an external electronic device biometric information of a user collected by the external electronic device;   a non-transitory memory that has previously-stored biometric information about the user; and   a controller that performs an authentication on the biometric information collected by the external electronic device by a comparison with the previously-stored biometric information, and controls the communication interface to transmit an authentication result to the external electronic device such that the external electronic device performs a predesignated operation.   
     
     
         13 . The electronic device of  claim 12 , wherein the biometric information that has an authentication performed thereon comprises one of iris information, fingerprint information, voice information, and pulse information. 
     
     
         14 . The electronic device of  claim 12 , wherein the biometric information is received from the external electronic device in a processed form using any one of coding or encryption. 
     
     
         15 . The electronic device of  claim 12 , wherein when the external electronic device comprises a Point Of Service (POS) device that requests a payment, the authentication result comprises at least one of payment information and security information. 
     
     
         16 . The electronic device of  claim 12 , wherein when the external electronic device comprises a wearable device that interworks with the electronic device, the authentication result comprises an instruction of controlling an operation of the wearable device, the instruction comprising at least one of an unlocking instruction and an application execution instruction. 
     
     
         17 . The electronic device of  claim 12 , wherein the communication interface receives identification information of the external electronic device together with the biometric information. 
     
     
         18 . The electronic device of  claim 17 , wherein the controller, after performing the authentication for the biometric information collected by the external electronic device, transmits the authentication result to the external electronic device using the identification information of the external electronic device. 
     
     
         19 . The electronic device of  claim 12 , wherein the controller, after determining whether a user of the external electronic device and a user of the electronic device are the same when the authentication is performed, controls the communication interface such that the electronic device transmits the authentication result to the external electronic device when the users are the same. 
     
     
         20 . The electronic device of  claim 19 , wherein the controller determines whether the users are the same using at least one of biometric information other than the biometric information, account information, or sensor information.
